There are some SATA controllers which have both devices 0 and 1 but this module
Do you mean a SATA port can connect to two SATA devices without PMP?
No, I mean 2 SATA ports combined in one ATA channel as 2 devices. Look for SLAVE_POSS in drivers/ata/[s]ata*.c...
Oh yes that happened when the SATA controller is in IDE programming mode, not AHCI.
AHCI is not the only mode for the SATA controllers.
ZPODD is only supported for SATA controllers in AHCI programming mode,
Hm, really? How about the true SATA controllers that don't use AHCI?
the ACPI table will not support power off the port if the controller is in IDE mode, so the device 1 case shouldn't happen in practice :-)
Anyway, I need uniform setup for ata_exec_internal() call for my to be posted cleanup patches.
Thanks, Aaron
